In the last Clauda Winkleman's Arts Show podcast there was a 5 - 10 minute interview with Alexander McCall Smith to coincide with the release of the newest in the No. 1 Ladies' Detective Agency series, Tea Time for the Traditionally Built. The podcast link is here though it seems the episode can only be obtained via iTunes or equivalent.
And, on last week's Book Reviews with Simon Mayo, one of the titles covered was Daniel Depp's Losers Town. The episode can be downloaded from here. Losers Town was described as a gumshoe mystery, the reviews were fairly positive though the book was thought to be not particularly original.
